Open bite of right ring finger w/o damage to nail, init

This code signifies an open wound on the right ring finger caused by a bite, where the integrity of the fingernail itself remains intact. This injury involves a break in the skin, potentially exposing underlying tissues, and is in its initial phase of treatment.

Apply this code when documenting a patient presenting with a fresh bite wound to their right ring finger. This is appropriate for animal bites (e.g., dog, cat) or human bites that have not yet received definitive medical care. It should be used for the first visit related to this specific injury.

• Ensure documentation explicitly states "right ring finger" and "open bite" without nail damage.
• Confirm the encounter is the initial treatment for this injury; subsequent encounters will use a different 7th character.
• Always code the external cause of the bite (e.g., W53.01XA for bitten by dog) in addition to this diagnosis code.
